[news.eclipse.platform.swt] Re: [browser] How to handle each display/she

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Hi Kamil,

This can only be done for SWT.MOZILLA-style Browsers, by providing your own
nsIPromptService via JavaXPCOM.  Note that once you do this then your prompt
service will be used for all Mozilla-based Browser instances regardless of
whether you created them or not (so this will be all SWT.MOZILLA-style
Browsers on win32 and OSX, and ALL Browser instances on linux).  A snippet
that demonstrates this is shown below.  For general information about using
JavaXPCOM in the Browser see
http://www.eclipse.org/swt/faq.php#howusejavaxpcom .  nsIPromptService is
documented at
http://www.xulplanet.com/references/xpcomref/ifaces/nsIPromptService.html .
